Derived Rees Matrix Semigroups as Semigroups of Transformations

Semigroup Forum, 2006
An ordered pair (e,f) of idempotents of a regular semigroup is called a skew pair if ef is not idempotent whereas fe is idempotent. Previously [1] we have established that there are four distinct types of skew pairs of idempotents. We have also described (as quotient semigroups of certain regular Rees matrix semigroups [2]) the structure of the ...

The ideal transforms of semigroups.

2003
Let \(S\) be a submonoid of a torsion-free (additive) Abelian group with quotient group \(q(S)=\{s- t\mid s,t\in S\}\), and let \(I\) be an ideal of \(S\). In analogy with commutative rings, the author defines the Nagata ideal transform of \(S\) with respect to \(I\) to be \(T_S(I)=\{z\in q(S)\mid nI\subset(S:_Sz+S)\) for some \(n\geq 1\}\) and the ...

On Coverings of Rough Transformation Semigroups

2011
The purpose of this paper is towards the algebraic study of rough finite state machines, i.e., to introduce the concept of homomorphisms between two rough finite state machines, to associate a rough transformation semigroup with a rough finite state machine and to introduce the concept of coverings of rough finite state machines as well as rough ...
